QOADING- DEVICE.

intensa Specication of Letters Eatent.

Patented Sept 1*?, iitd,

of an apparatus that is simple in construction an operation and which may be manipulated with facility at slight expense, but

'eat saving in labor.

The lnvention consists essentially in cer- 'tain novel combinations and arrangements of parts that are attachable to and detachable from the truck, and includes operative means that are actuated from the vehicle motor, as will he hereinafter described and claimedn 1n the accompanying drawings one complete example of the physical embodiment of the invention is illustrated, constructed and arranged according to the best mode so iar devised for the practical application of the principles of the invention.

Fi 're 1 is a plan view of the apparatus forming the sub] ect matter ci" the invention, illustrating its application to a motor vehicle.

y Fig. 2 is a iront elevation showing the supports ior the operating parts of the device.

Fi 3 is a view illustrating the manner of securing the necessary power from the vehicle motor.

1n the preferred embodiment of the invention as illustrated in the drawings the motor vehicle or, truclr is provided with the usual rectangular frame 1, and the rear springs 2 and rear wheels 3 are also depicted in Fig. 1 in order that a clear understanding of the invention may readily be secured.

Arranged' transversely of the channel irons that form the rectangular frame of the vehicle, are a plurality of holsters in the form of beams as 4:, 5, and 6, and at the ends these holsters are provided with the usual pockets or sockets 7 Ifor the reception of the customary Steves, not shown in the drawings.

The intermediate bolster 5 is specially adapted, i'or the present invention, and, like 'ate bolster, are journaled a pair of sheaves the other lbeams is' secured firmly to the frame oi' the vehicle and adapted to support a portion of the load of logs.

At one side of the center of the intermedior pulleys 8 and 9, which are' arranged on planes at an angle and the sheaves are located in clo'se proximity so that their grooves, or grooved peripheries, will prevent the escape of the rope or cable 10, which passes around one or the other of the two wheels. At each end of the intermediate bolster is journaled a vertically arranged pulley or idler 1l and 12, and the pulleys are adapted for use in pairs as 8, 11, and 9, 12, depending upon the side from which the logs are to be loaded on the truck. In connection withthe intermediate bolster, a special stave 13 is employed, and equipped with a vertically arranged sheave 14C at its upper end, over which the cable 10 passes, and at its end, the cable `is provided with the usual hook 15. 1n its normal position the stave is supported in the pocket 7 at the end of the bolster in the inclined or oblique angle as shown in Fig. 2, and at its lower end, which projects below the bolster, the stave is supported on aibrace arm 16 that is bolted at the sides of the bolster, and an `additional support is provided in the cleat-17, at the junction of the stave and brace arm, which prevents the stave from slipping.

At the opposite end of the intermediate bolster an additional and duplex brace 16 is provided so that the stave 13 may be removed from the side of the truck as shown in Fig. 1 vof the drawings and replaced at the opposite side, when such use is required.

The loading cable is wound upon the drum 25 which is loose on the shaft 18 that is journaled in the rectangular frame in close proximity t0 the motor engine 19, and power is transmitted from the vmotor to the drum shaft through thel interposition of the worin 2O (indicated in dotted lines Fig. 3) sprocket 100 chain 21, which is driven from the engine by a sprocket wheel (not shown) and a worm wheel within the housing 22, the worm wheel being' located on the shaft 18. Virhen the clutch member 23, keyed on the shaft 18, is 105 moved into contact with the clutch member 24 of the loose drum, the drum will be revolved from the motor of the truclr to wind the cable thereon, which, in its movement over the pulleys li l il as shown in- Fig. 2 it Will he evident that the' Alogs may he rolled entirely across the supporting frame, against the stake pins (not shown) at the near side of the apparatus in -l`ig. l, thus utilizing the maximum space on the'bolsters. sually three or four tiers of logs are placed on the truck in this manner, and the utilization of the loading mechanism eliminates considerableI time and labor in this operation.

. Claims- ,l l

1f The combination with a truck, its frame, and motor, of a log loading device including transverse holsters secured on the frame, and one of said holsters having a detachahle end-stave supported thereon and inclined to the perpendicular, a drum on the frame and means for operating it, a cable Wound on the drum, a pair-of guide pulleys on the said bolster forthe' cable, and a guide pulley at the upper end of thestave over which the end of the cable is purpose described.

2. The 'combination passed, Afor the with the rectangular frame of. a motor truck and a plurality ofi holsters arranged transversely and secured thereon, one offsaid holsters having an end wound on the drum and passed over said pulleys for the `purpose described.

- In testimony whereof I affix my signature.
